GlenRyan52;

Just how far apart do you want to take this shotgun? If you merely want to take the gun down you simply need to unscrew the barrel. To do that, pinch the knob at the end of the magazine tube and draw the tube forward towards the muzzle and then draw the pump arm forward until it clears the receiver. Then unscrew the barrel, bearing in mind, that the barrel threads are LEFT hand threads.
If you want to take the receiver apart, (which if I remember correctly, Brophy did not recommend unless a trained gunsmith), remove the butt stock by taking the butt plate off and the unscrewing the stock bolt behind the butt plate. Then you can remove the three (3) side plate screws on the right side to expose the action and internal parts. From there, you are on your own. I really suggest you do not disassemble the trigger assembly as that really could be a problem if you do not have the correct tools. There are parts diagrams in Brophy's book on pages 398 & 399 if you need help.
Good luck.....
Due to the increasing cost of ammunition, there will be no warning shot!
